# Barbel
A much more distinguished detail than meets the eye, becoming the defining feature of their face, like the signature on a painting.
**Short**
This type of barb is the most common on a koin. While they may be short, they’re very sensitive, and used to savor the world around them.
**Long**
Another common sight is koin with these long whiskers, but don’t be mistaken, this is not an indication of their age. They can be very young and carry them anyway!
**Deluxe**
Something about these not-so-common barbs make your koin look wise and mysterious. Might they actually be?
**Double**
Some barbs keep their style but duplicate their whiskers. Make it a double!
**Triple**
What’s better than two? Three! While not very common, it’s possible to find koins with a whole set of mustaches to show off.
**Spiral**
It's rare to come across a koin with such majestic barbs, but here's a secret: Once you do, they love to be praised. Feel free to indulge them!
**Warui**
It is impossible to stumble upon this rare barb and not think about its villainous appearance. Nothing could be further from the truth. All koins are friendly!
**Río**
Something about this unique barb makes us think of Carnaval. Warms beaches and lots of dances to show off!
